Configuring Jetty for Oracle CEP 11-5
11.2.5 Developing Servlets for Jetty
Oracle CEP supports development of servlets for deployment to Jetty by creating a standard Java EE Web Application and configuring it using the
Section 11.2.4, jetty-web-app Configuration Object.
11.2.6 Web Application Deployment
Oracle CEP supports deployments packaged either as WAR files or as exploded WAR files, as described in version 2.4 of the Java Servlet Specification.
You can deploy pre-configured web applications from an exploded directory or WAR file by including them in the server configuration.
Security constraints specified in the standard web.xml file are mapped to the Common Security Services security provider. The Servlet API specifies declarative
role-based security, which means that particular URL patterns can be mapped to security roles.
11.3 Example Jetty Configuration
The following snippet of a config.xml file provides an example Jetty configuration; only Jetty-related configuration information is shown:
